This is just not the case. Quill stems are not like seat posts*.
*Threadless* stems are more like seat posts. With quill stems the stem HAS
to be undersized so you can get
Also & regarding Garth’s comments regarding the possibility of this Clem L being too small for me; Mine is a 52 & “should” be correct for me according to Riv sizing suggestions. I have put nearly 6,000 miles on this bike and dearly love it. But, I think I’d have been very comfortable going one
This pic shows how far into the head tube my stem currently extends. The
minimum insertion line is 2 cm below the lock nut. FWIW, I do not notice
any movement riding the bike. I only notice it straddling the bike, feet on
the ground & putting my full weight into the grip area of my Bosco bars.
Garth, thanks but not certain I understand. You say (I think) minimum insertion is “always to top of lock nut”. My minimum insertion mark is 2cm below top of lock nut. The quill goes quite a bit deeper to well below top of steer tube. I will remove to get an accurate measurement but it is quite
You know, Bill… after reading your comment here I had to go take a look at
my Appaloosa and wouldn’t you know it, you’re right! There’s some play in
it! It’s not as pronounced as the video Richard shared but it’s there to be
sure! I’d never noticed it before. Perhaps the others are in correct and

Since you've measured your stem at 22.2mm and since you perceive the same
wiggle with two stems, that rules out an undersized stem. That gives you
two choices:
-live with it. It's one of the minor shortcomings of quill stem bikes,
made more noticeable with a really tall stem and presumably
Regarding item #1, stem measures 22.2 & of course it is a 1” steer tube. Seemed unliked Riv would sell a stem for one of their bikes that was the wrong size, but worth checking for sure.Regarding item #2, I did remove & replace stem & it did not change. I remember reading that the minimum
Couple of thoughts right off:
1. if you pull the stem out to the minimum insertion line and re-tighten
it, does it still move? Sometimes, if you've inserted the stem too far, you
may encounter this issue. It can be mitigated by getting a shorter stem or
cutting the current one down a bit
Greetings folks. I would appreciate any input regarding this. Since new I
have had some movement in my headset / stem that concerns me, possibly
unnecessarily so? Please review the attached video link and tell me what
you see. I felt the headset was a bit loose so tightened it a bit. This

Here are two things that I’ve learned:
Be careful and don’t tighten it down too much. You can damage the races.
That being said, tighten the adjustable part just a bit beyond where the play
in the bearings is removed, then lightly tighten the locknut down, and finally
loosen the
This is a needle bearing IRD Rollerdrive just like Riv sells.
1. Loosen lock nut
2. tighten the nut under the spacers 1/8 turn
3. Tighten lock nut.
4. test for correct feel.
5. Readjust if.
Is this right?
Anything to look out for?
Do I have to worry about those keyed spacers or anything else
My Rivs have all had 32 mm flats on the headset bits. I'd get a 32 mm
adjustable cup wrench, and spend the change on a big, decent quality
adjustable wrench which is also useful for bb assembly removal and hitting
the dog. (And for many other things; just kidding about the dog; he's
already cowed
Yes, all 1-inch threaded headsets use a 32mm adjusting nut. You only need one
32 wrench for the adjuster, the locknut can be snugged down with a standard
crescent (adjustable) wrench.

Hi all,
I was going to attempt a headset adjustment, which I've never done. I need
to buy two wrenches to do the job. It's probably obvious to others, but I
can't figure out what size wrench to buy to adjust the headsets on my
Rivendells. Are they all going to be 32 mm? That appears to be the
